PS3003L – DC-REGULATED POWER SUPPLY WITH DOUBLE LCD DISPLAY

1. Introduction & Features

To all residents of the European Union Important environmental information about this product

This symbol on the device or the package indicates that disposal of the device after its lifecycle could harm the environment. Do not dispose of the unit (or batteries) as unsorted municipal waste; it should be taken to a specialized

company for recycling. This device should be returned to your distributor or to a local recycling service. Respect the local environmental rules.

If in doubt, contact your local waste disposal authorities.

Thank you for buying the PS3003L! Please read the manual thoroughly before bringing this device into service. If the device was damaged in transit, don't install or use it and contact your dealer. The PS3003L is a highly accurate, DC-regulated power supply with an adjustable output. This output can be used for constant voltage (C.V.) and constant current (C.C.). The current-limiting point can be set arbitrarily in this mode. The output current and voltage are indicated through LCD displays.

4. Operation

1) Using the device as a C.V. source

Turn both current adjustments (3) to the extreme right prior to activating the device. Activate the device. The current-limit protection can be set arbitrarily. Connect a proper variable load and adjust its resistance to make the current equal to the protection point. Meanwhile, fine-tune the current adjustments (3) to let the C.C. indicator in critical state.

2) Connecting the Load

The load is connected as shown in the figure above. You can read the output current (2) and the output voltage (1) from the display as soon as the device has been switched on. The C.V. indicator (8) is lit if the device is in the C.V. mode. The C.V. LED is off and the C.C. LED will light if the Amp display indicates a value that exceeds the installed value. When this happens, the device will automatically go into the current-limiting mode. Install a load that will allow the device to function normally.

3) Using the device as a C.C. source

Use the power switch (7) to activate the device. Turn adjustments (4) to the extreme right and turn adjustments (3) to the extreme left. Connect the load. Adjust (3) until the desired current is obtained.

5. Safety Prescriptions

• The PS3003L enjoys optimal protection thanks to the short-circuit protection and the current-limiting point.

However, the power loss of the power transistors is maximal in case of a short circuit. Consequently, the device should be switched off in order to protect it from damage.

• Store the device in a dry and well-ventilated environment and wipe it clean regularly with a damp cloth. Remove

the power plug if the device is to be stored for a prolonged period of time.

• Cut off the input voltage prior to cleaning the device.

• This device is a large power source. The device should be well-ventilated when working at max. power in order to

avoid overheating. Keep in mind that the surface of the heat sink is too hot to touch when the device is being used at max. power.

• Improper operation of the device and an excessive ambient temperature may cause certain internal components

to fail. When this happens, the actual output voltage may exceed the rated output voltage. PROCEED WITH CAUTION WHEN USING THIS DEVICE AND AVOID UNNECESSARY DAMAGE TO THE LOAD.

• The 3-pins ground terminal of the power cord should be grounded securely in order to ensure safe operation of

the device.
